Scientists from the RIKEN Quantitative Biology Center (QBiC) in Japan have generated power from a torpedo ray in the lab. The scientists removed the electricity producing organ from a torpedo and chemically stimulated the organ by injecting a solution of the neurotransmitter acetylcholine though a syringe. They were able to achieve more than a minute […]

A team led by Concordia University engineering professor Muthukumaran Packirisamy describe their new invention as a power cell that harnesses electrical energy from the photosynthesis and respiration of blue-green algae. The study paper has been published in the journal Technology. Packirisamy explains, “Both photosynthesis and respiration, which take place in plant’s cells, involve electron transfer […]

Stanford University engineers have devised a new way to generate electricity from sewage using naturally occurring “wired microbes” as mini power plants.  The exoelectrogenic microbes produce electricity as they digest plant and animal waste. The laboratory prototype is about the size of a D-cell battery and looks like a chemistry experiment, with two electrodes, one […]
